Robert Frost once suggested that a poem is a pithy form of expression that, by definition, can never be translated accurately. The same can be said about mathematics: The best way to understand and appreciate the beauty of an equation is to see it in its original, coded form. *In Five Equations That Changed the World*, Dr. Michael Guillen, known to millions as the Science Editor on ABC-TV's *Good Morning America*, reveals in simple, everyday language the secret world of mathematics through the amazing stories of the people and discoveries that led to the five most powerful and important scientific achievements in human history. It was through the brilliance of these five fascinating people that we were able to harness the power of electricity, fly in airplanes, land astronauts on the moon, build a nuclear bomb, and understand the mortality of all life on Earth. But behind these discoveries are gripping dramas of jealously, fame, war, and debate. Dr. Guillen vividly brings to life these chronicles of science by going behind the scenes and revealing the political conflicts, social upheaval, religious sanctions, family tragedies, and personal ambitions that contributed to each man's indelible place in history. The world of mathematics comes to life in *Five Equations That Changed the World* in a way that will entertain as well as enlighten.
